Device for orderly arranging cops and spool cores for textile machines

ABSTRACT

THE ARRANGING THE CORES, WHICH ARE OF FRUSTOCONICAL SHAPE THE DEVICE COMPRISES AN UPPER PORTION THROUGH WHICH THE CORES CAN FALL INTO THE LOWER PORTION PASSING WHICH THEIR THINNER END THROUGH EITHER TWO SLOTS, WHEREBY THE THINNER END CAN FIRST FALL ON A STOP BAR AND SUBSEQUENTLY THE THINNER END FREELY FALLS DOWN, THINNER END BEING THUS ALWAYS DIRECTED UPWARDLY.

PATENTEU JUN28 1971 SHEET 1 BF 2 DEVICE FOR ORDERLY ARRANGING COPS AND SPOOL CORES FOR TEXTILE MACHINES This invention relates to a device for orderly arranging cops and spool cores for textile machines.

In general conical spinning and/or twisting cops or spool cores generally which have one extremity narrower than the other, for example cops for spindle frame spools, shuttle cores for looms etc. have to be arranged in an orderly manner in suitable containers when they are intended to feed special equipment, such as automatic loading devices.

The term orderly manner" implies that the cops or spool cores must be arranged all orientated with their axes and direction of taper, or narrower side, in the same direction.

This requires much time on the part of the operator responsible for this operation.

The device according to the invention allows this operation to be considerably shortened in that, by its adoption, it is suffcient to arrange the cops or spool cores in the requisite container taking care only that these are orientated with their axes in the same direction, but without taking into account their orientation in the direction of taper or the narrower side.

The device comprises a truncated pyramidal boxlike body with its substantially rectangular base of larger area arranged horizontally upwards and provided with the feed port for receiving the individual cop arriving in the horizontal position, while the smaller opposite base is provided with the outlet port for exit of the cop in the vertical position, there being mounted inside said body two symmetrical plates arranged as chutes towards the inside, underneath the two extremities of the feed port, each plate having a central longitudinal slot of width less than that of the wider side of the cop and greater than that of the narrower side, and being further provided internally and below said plates with two transversal bars and two impact plates mounted symmetrically to each other which cause capsizing by gravity of the cop and its exit from the lower outlet in -the vertical position with the wider side downwards.

The device is illustrated for greater clarity by way of example in the accompanying drawings in which:

FIGS. 1 and 2 are a vertical section through the device in tow operating positions;

FIGS. 3 and 4 show the same view from above;

FIG. Sis a lateral view of the device.

FIGS. 1 and 2 show clearly the operating principle of the device for orderly arranging, which is figured using conical spinning cops, however it is to be understood that the operation would be identical using spool cores of different form than those shown.

Consequently in the following when the word cop" is used, it is intended that this should be taken as meaning both the conical cops for spinning and twisting, and any other cop or spool core for textile machines having one extremity of greater diameter than the other.

The cops are transported one at a time to the feed port by means of a conveying apparatus not shown in the FIG. and inessential to the understanding of the orderly arranging device, after having been taken from their container, which is not shown.

FIGS. 1 and 2 show the two possible cases, in that in which the cop is arranged at the feed port with its taper in one direction and that in the other direction. If the device is dealing with cylindrical tubes with one larger extremity or spool cores for looms instead of conical cops, it must be imagined that the FIGS. 1 and 2 represent the two cases in which the cylindrical tubes or spool cores are arranged with the narrower side to the right (FIG. 1) or to the left (FIG. 2).

The device for orderly arranging is arranged vertically and the feed port 1 is situated in its upper part. Its operation is caused only by the force of gravity and the device has no movable mechanical parts. Two equal plates 3 and 3' are symmetrically arranged at the feed port 1, each having a slot of such a width as to permit the passage of the narrower side of the cop but not the wider.

Consequently the cop, abandoned by the conveyor in the position 2, will cross through the slot on the plate with its narrower part by the force of gravity, but will slide on the other.

The cop 2 is shown in eight successive positions 2' to 2 during its fall.

Two bars, 4, 4' and twoimpact plates'5, 5' are arranged in a suitable adjustable position inside the device, their function being to capsize the cop as described below.

In the position 2 the cop is shown as it is crossing through the slot in the plate with its narrower side (plate 5 in the case of FIG. 1; plate 3 in the case ofFlG. 2).

In the position 2, the cop has arrived at one of the two capsizing bars 4 and 4' and the impact plate 5 or 5'.

The tube then capsizes pivoting around said bar (position 2" to 2) and becomes arranged at the lower outlet 6 in the vertical position always orientated with its narrower side upwards.

If suitable collecting members, not shown in the FIGS., are provided at this outlet, then the cops will always reach them orientated in one direction whatever their orientation at the feed port I of the described orientation device is.

It is clear that the device described permits conical cops to be orientated which are fed with their axes in one determined direction but without taking account of their direction of taper. It also permits cylindrical tubes provided with an enlargement or ring at one end for textile machines to be orientated, such as for example spindle frame spools which are fed with their arms in one determined direction but without taking account of the position of the enlargement or ring. It likewise permits spool cores for looms to be orientated which are fed with their axes in one determined direction, but without taking account of the position of their end enlargement.

lclaim:

l. A device for orderly arranging cops and spool cores for textile machines comprising a truncated pyramidal boxlike body with its substantially rectangular base of larger area arranged horizontally upwards and provided with a feed port for receiving the individual cop arriving in the horizontal position, while the smaller opposite base is provided with an outlet port for exit of the cop in the vertical position, there being mounted inside said body two symmetrical plates arranged as chutes towards the inside, underneath the two extremities of the feed port, each plate having a central longitudinal slot of width less than that of the wider side of the cop and greater than that of the narrower side, and being further provided internally and below said plates with two transversal bars and two impact plates mounted symmetrically to each other which cause capsizing by gravity of the cop and its exit from the lower outlet in the vertical position with the wider side downwards.

2. A device as claimed in claim 1, in which its members are fixed and immobile during operation.

3. A device as claimed in claim 1, in which the conical cops or cylindrical tubes provided with an enlargement or the loom spool cores are orientated during their falling movement by gravity from the upper feed port of the device to the lower outlet port.
